Mahogani,
I get my semi-thick eyebrows threaded at The Bombay Salon.
This salon specializes in eyebrow threading.
A string/thread is used to pull individual hairs.
The results are precise and my arch is natural looking.
I go once a month to get a SHAPE-UP.
I believe the $7 FEE is reasonable, as well!
If you're interested, the address is:
80 West 36th St. @6th Avenue. (South East Corner)
Tele (212) 695-1111 *Ask For Maju or Rozy*
